New Delhi, Mar 29 (PTI) Researchers have developed a three-dimensional (3D) paper-based portable device that can detect adulteration in milk within 30 seconds.

The test, which could be performed at home, can detect multiple commonly-used adulterating agents including urea, detergents, soap, starch, hydrogen peroxide, sodium-hydrogen-carbonate and salt, among others, they said.

Requiring only a millilitre of a liquid as a sample for the test, the researchers said that the test can be used to detect adulteration in other liquids as well such as water, fresh juices and milkshakes.
